STOVE ATTACHMENT.

Specification of Letters Patent.

Patented Feb. 4, 1 908.

Application filed March 15. 1905. Serial No. 250.210.

T 0 all whom it may concern:

Be it known that l, MARIE E. l/VQOD, of Brooklyn borough, New York,county of Kings, and State of New York, have invented a new and usefulStove Attachment, of which the following is a specification.

The object of my invention is to provide a removable grate covering andpartition, that is adapted to be placed in the furnace compartment of anordinary stove or range thereby covering a portion of the grates andreducing the size of the furnace so that when the maximum capacity ofthe stove is not required a smaller fire can be burned to betteradvantage and with greater economy of fuel. I accomplish this objectwith the device illustrated in the accompanying drawing in which Figure1 shows the device placed in the furnace of an ordinary cook stove. Fig.2 is a perspective View of the device showing some of its constructivedetails. Fig. 3 is a horizontal section cut on the dotted line 1, 2,Fig. 2, andFig. 4 is a vertical section cut on the dotted line 3. 4.Fig. 2.

Similar letters refer to similar parts throughout the several views.

In Fig. 1. C represents the device placed in the furnace of a stove, theoutside walls and top of the stove being cut away in order to show theinterior. M. is the side wall of the furnace and N. the back wall and G.is the grate.

In Fig. 2. the angle plate A. which I will call the central angle plate,over laps the two angle plates B. B. (which I will 'call the side angleplates) and is secured to the same by the bolts 1). b. which projectthrough the slots 6. c. the heads of which fit in counter sunk holes inthe angle plates B and B. the slots 6. 6 permit of an adjustment to awidth that will suit different sizes of furnaces. O. is a cement or clayfacing. H. is a hole in the web W. into which a hook may be inserted andthe entire device lifted bodily out of the furnace, and when desired bereplaced. W. is a web to strengthen and prevent the warping of thecentral angle plate A.

In Fig. 3. the lugs L. L. are cast integral with, and on the verticalfaces of the angle plates A. B. B. and are formedin order to firmly holdthe clay O.with an increasing diameter which enlarges the further theyproject from the angle plate. The angle projections F. F. on thevertical edges of the side angle plates B. B. are made so that theiradjacent faces a. a. in reference to each other will be a form of thewell known dove tail joint which holds the clay C. more firmly; theadjacent vertical edges (1. a. of the angle plates B. B. also form adove tail joint with the clay, O. The angle projection F. Fig. 4. at thebottom edge of the vertical faces of the side angle plates, B. B. andthe dotted lines F. F. Fig. 3. is a protection to the lower edge of theclay facing, O.

In adjusting the device to a stove the bolts 5. b. are loosened, thethree angle plates are placed in the furnace of the stove in referenceto each other as shown in Fig. 2. The side angle plates B and B are thenadjusted to the width of the furnace, then the bolts 1). Z). are madetight; the plates are then lifted from the furnace and a coating of somefire resisting cement, such as fire clay and fire brick dust mixed withwater, is placed on the faces of the angle plates as shown at O. thecoating covering the lugs, L. and fitting into the dove tail recessesformed by the faces and edges a a a a. After the water dries out thehook is inserted in the hole, H. and the device is placed in the furnaceso that the bottom faces of the angle plates cover that portion of thegrates represented by G. Fig. 1. the fire then being made on the portionnot covered.

What I claim as my invention and wish to secure by Letters Patent is,

1. A stove attachment comprising a central angle plate providedwithtransverse slots and with a strengthening web having an opening, sideangle plates provided with holes or openings adapted to register withthe slots in the central angle plate, the vertical outside faces of theside angle plates being provided at their side edges with out wardlyextending flanges having inner angular sides adapted to form a dove-tailrecess, a facing of cement covering the vertical faces of the angleplates and fitting in the dove-tail recess, and bolts passing throughthe slots and the holes in the plates to retain the parts in adjustedpositions.

2. A stove attachment comprising a central angle plate provided withtransverse slots and with a strengthening web having an opening, sideangle plates provided with holes or openings adapted to register withthe slots in the central angle plate, the vertical outside faces of theside angle plates being provided at their side edges with out- Wardlyextending flanges having inner angular sides adapted to form a dove-tailrecess, a facing of cement covering the vertical faces of the angleplates and fitting in the dovetail recess, lugs with enlarged endsprojecting from the face of said side angle plates into and securingsaid facing of cement, and bolts passing through the slots and the holesin the plates to retain the parts in adjusted positions.

3. A stove attachment comprising a central angle plate provided Withtransverse slots and With a strengthening Web having an opening, sideangle plates provided With holes or openings adapted to register Withthe slots in the central angle plate, the vertical outside faces of theside angle plates being provided at their side edges With outwardlyextending flanges having inner angular sides adapted to form a dove-tailrecess, a facing of cement covering the vertical faces of the angleplates and fitting in the dovetail recess, lugs with enlarged endsprojecting from the face of said side angle plates into and securingsaid facing of cement, flanges projecting from the bottom of theVertical outside faces of said side angle plates, and bolts passingthrough the slots and the holes in the plates to retain the parts inadjusted positions.
